;To all whom it may concem i section a 'hinge, door,

- which Be it known that I, S. HEEBERT GIESY, of Washington, in the District of Columbia, have invented certain new and useful Improvements in Dcor-Checks, of whiqh the following is a specification. i

The object of my invention is to provide a simple iuexpensive door-check to 'limit the movement of a door when opened and prevent it from striking against an adjacent wall or other contignons object.

Various devices have heretofore been ernployed for this purpose; but they have all been i more or less complicated, expensive, and .ineliieient.

My invention is 'extremely simple and inexpensive, and may readily be applied to any door or similar structure. i

In the acconpanying drawings, il-lustrating my invention, Figure 1 is a View showing in and door-frame with my improved door-check in position. Fig. 2 is a similar view showing a modified form of my invention, -and Fig. 3 is a side view of the same.

A met-allie ring, a. is provided with a laterally-projecting shanit, b, to which is attached a huifer-block,'c, preferably of rubber or other similar slightlyrelastic material. The shank b is preferably screw-threaded on its-enter end, projects through the block and receives a nnt, d, which firmly secures the block to the shanit.

The block c is preferably shaped as shown in Fig. 1, so as to be readily applied to an ordinary door hinge. As shown in this figure, the block has a straight plain end, c', a reat angular notch, 0 .and astraight side, c, at right angles to the end c'. The side c* may he shapedasdesired, preferably curved, asshown. A block of this shape is suitable to peruit a door to open at. right angles to the adjaeent wall.

When it is desired to have the door open wider, as at an angle of forty-five degrees to' the adjacent wall, the notch e is made with an angle of one hundred and thirty-five degrees, and the side e should be at an angle of forty-five degrees to the side c'; By thue varying the angle of the notch and the angle of the side e* the angle to which thedocr may he opened relatively to theadjacent wall may be regulated. Of course other ways of adapting the shape of the block to .regulate the movement of thedoor besides those suggested' may he emplbyed. r

The deviee is applied to ahinge by-slipping the ring a over the pintle hof a door-hinge he tween its leaves, so as to allow the shank 25,

carrying the butter-block c, to project away from 'the hinge between the door' and the adjacent wall. The end e' :of the block rests against the wall or door-frame, and the soeket of the hinge lies in the notch c When the door is opened to the limit of its movement, it

ring a may be made so thin as not to afi'ect appreciably the hanging of the door, and, being 'o'f hard metal, it will stand ordinary wear without material waste. 'When the ring a is placed' on a pintle, between the leaves of a hinge, it serves as a washer.-

When the device is applied 'to that class of hinges which employ a ring between the leaves, size and thickness ployed.

I preferably apply my improved door-check to the upper hinge of a door; but it may be applied to all the hinges, if desired.

I claim as my invention- 1. The eombination, substantially as herein before set forth, of the buffer-hlock, the laterail y-proj eeti ng shank, and the ring on the enter end of the shank for securing itto a hinge.

2. The combination, substantially as set for-th, of a door-hinge, a bufier block, c, having an end, c', adapted to rest against a' frame or adjacent walka notch, to form aseat for the hinge soeket or sockets, and a side, c, at an angle to the end a', against which the door or similar structure abuts, and the shank b, car: rying the buEer-block and secured to'the hinge midway between the leaves thereof.

In testimony whereof I have'hereunto suhseribed my name.
